Juli2301 [7.4K]

ANSWER

g(x) =  \sqrt{x + 4}

EXPLANATION

The parent square root function is

f(x) =  \sqrt{x}

The translation

g(x ) =  \sqrt{x + k}

Will shift the graph of f(x) k units to left.

The translation

g(x) =  \sqrt{x -k}

will shift the graph of f(x) to the right by k units.

Therefore if f(x) is shifted 4 units to the left its new equation is:

g(x) =  \sqrt{x + 4}

Geometry Question Help if you can please
docker41 [41]

Answer:

≈ 78.55 cm

Step-by-step explanation:

Using the ratio of arc (AB) to circumference (C) is equal to the ratio of angle subtended at centre by arc AB to 360°, that is

\frac{AB}{C} = \frac{110}{360} , that is

\frac{24}{C} = \frac{110}{360} ( cross- multiply )

110C = 8640 ( divide both sides by 110 )

C = \frac{8640}{110} ≈ 78.55 cm ( to 2 dec. places )

Round the mixed number to the nearest whole or half. 11 5/6
Luba_88 [7]
11 5/6 as a decimal would be 11.83. Then, rounding that to the nearest whole number would be 12. Giving you an answer of 12.
